ULTRAVIOLET-RAY MACHINE.

Application filed December 14, 1927. Serial No. 240,048.

This invention relates to means for producing ultra-violet rays and has Jfor its primary object, the furnishing `oli such means in a very simple, etlective structure at an extremely low cost ot production.

The invention is described hereinbelow i reference to the accompanying drawing, in whichy Fig. 1, is a front elevation of a device embodying my invention;

Fig. 2, an enlarged rear elevation of the upper structure of the device;

Fig. 3, a top plan vi ew otl the device;

Fig. 4, a section on the line 44 in F Fig. 5, a section on the line 5-5 in Fig. and' Fig. 6, an end elevation oi? that parl` of the device as shown in Fig. 2.

Lilie characters o'lf reference indicate like parts throughout the several views of the drawing.

0n a stand having a base 10 anda vertically7 extending post 11, I mount a horizontally eX- tending bar 12 by means of a bracket 13 tixed to the bar 12 at one end and aidingly passed over the post 11 whereby the bar 12 may be raised or lowered on the post l1, or swung horizontally around the post l1, and the bar 12 will remain at any elevation on the post 11, by reason of the Outer end ol the bar 12 tend ing to drop downwardly which causes the bracket 13 to grip the post.

Near the bracket end et the bar 12, I piv* otally attach an arm 1 4 on the bolt 15 and alace a spring 16 on the bolt to be compressed by the thumb nut 17 against the arm 14 through the washerslS and 19, so that the arm 14 may be swung about the bolt 15 and will remain at any position to which it may be moved. Spaced out on the bar 12 from the bolt 15 is a spring clip 20, and asimilar spring clip 21 is carried by the arm 14. Screws 22 and 23 are screw-threadedly passed through the arm 14 and bar 12 respectively to bear against the clips 21 and 2O so that by passing the screws through the bar and arm the clips may be pressed outwardly therefrom to receive the therapeutic carbone 24 and 25 thereu under, whereupon the screws 22 and 23 are withdrawn from contact with the clips to permit the clips to press and firmly hold the carbone respectively against the bar and arm. The clips 20 and 21 are positioned to hold the carbons 24 and 25 at the same radialy distance from the bolt 15.

The carbons 24 and 25 are adjusted longi-k tudinally under the clips 20 and 21 to have their ends meet, as in Figs. 1 and 2. A two wire cable 26 is connected by one end to a suitable source of alternating electric current (not shown) and is held by the other end under a clamp on the bar 12, from where one of the wires 28 of the cable 26 is led to the control switch 29. The other wire 30 of the cable 26 is carried along back of the bar 12 to include in parallel connection the two resistance elements 31 and 32 and thence back to be secured to the bolt 15 to include the arm 14 in the circuit. The arm 14 is electrically insulated from the bar 12. The switch 29 when turned to the on position interconnects the wire 28 with the bar 12 (not shown).

A liber rod 33 is pivotally secured to the outer end of the arm 14 as a means of moving the arm 14 without the operator having to touch the charged arm 14. lVith the switch 29 turned to the on position, an electrical circuit is established through the resistanees 31, 32, the bar 12, the arm 14, and the carbons 24 and 25.

The rod 33 is pushed upwardly slightly to create a gap between the ends of the carbons to establish an arc thereaeross, from which are radiates the desired ultra-violet rays. By reason of the uniformity of the therapeutic carbons and the use of alternating current each carbon 24 and 25 will be equally consumed and the point of the upper carbon may always be contacted upon the point of the lower carbon by pulling down on the rod 33, by reason of the arcuate travel of the upper' carbon.

l/Vhile I have here shown my invention in one particular form, it is obvious that the structure may be varied without departing from the spirit of the invention, and I do not desire to be limited, therefore, to the precise structure as shown, nor any more than may be necessitated by the following claims.

I claim 1. A new article of manufacture comprising a vertically supported post, a horizontal bar adjustably carried on the post, an arm pivoted on the bar, a carbon carried by the bar and a carbon carried by the arm whereby the end of the arm carbon may meet the end of the bar carbon on an are having the pivot point of the arm as its center of curvature.

2. A new article of manufacture comprising a vertically Supported post, a horizontal 5 bar adjustably carried 0n the post, an itl-1n pvotecl 0n the bar, L carbon carried by 'the bar and a carbon carried by the arm whereby the end of the arm carbon may meet the end ot' the bar carbon 0n an are having the pvot point of Vtbe arm as its Center of eurvutlue :unl friction means resisting the movement O't the arm.

In testimony where/ol l u'flix my signature.
